The formation control of second-order multi-agent system under wireless network with communication constrains and uncertainty is investigated in this paper. The binary sequence is used to design the agent scheduling protocol for the media access constrains in wireless network, where only the sampling information of the agents which satisfies the constraints is allowed to transmit through network. On the other hand, in order to build more realistic communication channel model, the wireless network metric is used to construct a new topology model rather than the traditional fixed interaction weights, which considers the uncertainties of wireless network and also the relationship between interaction weights and the distances among agents. Furthermore, the second-order multi-agent system model is transformed into close-loop system model with timedelay by defining information updating error and formation error. The formation control scheme is then designed by constructing Lyapunov Krasovski function and taking advantage of LMI techniques. Finally, a simulation example illustrates the effectiveness of the proposed method.
